Abstract
Tin-doped (Sn-doped) TiO2 nanorods arrays were successfully synthesized on a TiO2 seed layer via a mild one-pot hydrothermal method. Sn-doped TiO2 nanorods with high electron mobility were assembled into a solid perovskite solar cell. The study indicated that the introduction of the Sn element led to the change of the TiO2 band gap from 3.0 to 3.04 eV. Electrochemical impedance spectroscopy showed that the resistance of the device based on Sn-doped TiO2 nanorods was lower than that of the undoped device. The PCE of the Sn-doped perovskite device achieved 6.31%, which was almost 67% higher than that of the undoped sample.Keywords
